Radiation Hardware
Radiation Hardware Quiz prep, practice quiz etc
| Question | Answer |
|---|---|
| The warming sleeve on the power injector is designed to keep contrast at a temperature of about: | 37 degrees C |
| A patient's angulated x-ray view is 60 degree LAO, 30 degree cranial. In this view the image intensifier may touch the patient's | Left shoulder |
| A contrast agent with an osmolarity of 300 milliosmoles would be considered: | Iso-osmolar |
| A bulging or aneurysmal LV wall segment is termed: | Dyskinetic |
| When you increase the X-ray tube filament temperature, you are increasing the: | mA - you get more dots with more heat |
| T or F- X-rays can cause tissue damage because when they strike an atom of human tissue they may remove an orbital electron | True |
| T or F? Internal mammary bypass grafts can be studied easily from the contralateral brachial approach | False, should be ipsilateral/ same side for best view |
| When power injecting an LV gram which of the following would not be a setting that you could enter to direct the injection? Rate of rise or transition time; viscosity constant for contrast; pressure limit; duration of injection; vol. of injectate | Viscosity constant for the contrast |
| What component of an X-ray system is positively charged? | Rotating tungsten anode |
| The resolution in line pairs/mm of an imaging system describes all of the following EXCEPT: Image sharpness; Visibility of anatomical detail; Depth of penetration; Differentiation between closely spaced objects; Discrimination of small structures | Depth of penetration |
| Characterstic radiation refers to x-rays generated by: | dislodging a K-shell electron |
| Which of the following angiographic views would best display the aortic arch vessels? | 45 LAO |
| In new x-ray systems, flat panel detectors are currently replacing the: | cylindrical image intensifier |
| 99% of the energy used by the x-ray generator exists in the form of: | waste heat |
| Collimation of the x-ray beam involves filters made of: | Lead |
| The rotating anode in the x-ray generator is made of : | Tungsten |
| Chest leads made of carbon filament do not show up under fluoroscopy because they are: | radiolucent |
| The most damaging radiation comes from the | primary beam |
| One Sievert = | 100 REM |
| 100 RAD's = | 1 Gray |
| in soft tissue 1 Gray approximately equals | 1 Sievert (in soft tissue Grays and Sieverts are the same; 1:1) |
| Landauer reports indicate film badge exposure in | Millirems |
| The reduction of electromagnetic energy as radiation passes trhought matter is called: | Attenuation |
| The iodine in contrast is: | Radio-opaque |
| Can x-rays be focused using electrostatic lenses? | No, there is no charge in x-rays |
| Ionizing radiation damages tissue by: | removing an orbital electron |
| mAs determines: | the number of photons being produced |
| Coronary angio on a large pt in a steeply angulated view: the primary change made by the automatic cine exposure system to maintain adequate penetration is to increase: | kV |
| Which of the following effects both the quality and quantity of the primary x-ray beam? kVp; mA; mAs; Exposure time; None of the above | kVp because it also increases the mA |
